AT'li-lCl-IllflslNT FOR WILFLEY TABLES.

Specification of Letters Patent. Patented Nov. 15, 191%.,

Application filed March 19, 1909. Serial No.484,451.

To all whom it may concern:

Be it known that I, WALTER F. SMITH, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Im )rovements in Attachmentsfor VVilfley Ta les, of which the following is a specification.

The recovery of concentrates by means of -VVilfley or similar types of tables is Well understood and it is the object of my invention to improve this recovery and additionally separate and separately recover some or all of the different ingredients of the concentrates.

To this and other ends hereinafter set forth the invention comprises the imrovements to be presently described and nally claimed.

In the accompanying drawings, Figure 1, is a top or plan View illustrating the concentrates discharge end of a VVilfiey table having in application thereto means embodying features of the invention. Fig. 2, is a sectional view, drawn to an enlarged scale, and taken on the line 22, of Fig. 1., and Fig. 3, is a sectional view taken on the line 3--3. of Fig. 2.

A \Vilfley table is well understood and a full description of it can be found in ()re' Dressing, Vol. II, page 670, by R. H. Richards, published 1906, by The Engineering and Mining J omn'al at New York. is no need to illustrate this complete device so that in the drawings 1, is the concentrates discharge end of such a table audit, as is well known, is jerked back and forth on a suitable support 2. The concentrates pass over the concentratesdischarge end of the table and the gangue rolls over to the tail side.

more 01' less "sharply defined in passing off the concentratesdischarge end of the table.

3-9, indicate such positions but these posi- There 10, is a rifiie arranged at the concentrates discharge end of the table so as to receive those concentrates of the same kind which leave the table at generally the same point of discharge, for example, the point 8. Inasmuch as this point of discharge 8, is varialole across the table, I make the riflie movable across the table so that it may be adjusted to the point of discharge thus receiving the same kind of concentrates. For this purpose the rifile 10, is mounted in a cradle or frame 11, slidable on Ways 12 and 13, arranged in the walls of the box or receptacle 14.

15, is a rod connected with the cradle and with a lever 16, by means of which the rod, cradle and ritlle can be moved crosswise of the table.

17, is a perforated pipe arranged at the upper end of the rifiie and supplied with Water by means ofa flexible connection 18. Of course the number of movable riftles can be increased or diminished but an illustration and description of one is suflicient for an understanding of the invention.

21, is a chute shown to consist of a bottom, a side and an end. It is mounted on and arranged at the inlet end of the riflle 10, and serves to deflect from the riiile material not intended to enter it.

19, is a small box or receptacle into which the contents of the movable riffle is discharged. The kind of concentrates Which by reason of their specific ravity reach the movable rifile, are delivered by it into the receptacle 19, where they are kept separate from the other kinds of concentrates. If the concentrates which pass over the movable rifile contain gold, quick silver or mercury is applied to the riflles and serves to separate the gold by amalgamation. Moreover the from the tableto the. riffie are cleaned and with co-actin rubbing surfaces, the chute made easily susceptible to amalgamation by being adjusta 1e transversely of the end of the mercur These rubbing surfaces may the table.
